2003 CR250 Tuning.

[JD-250]

I see quite a few people who have jetting issues with the 01'-03' CR250's. I must be lucky because my 03' CR250 runs awesome with the stock jetting. It accelerates clean from bottom to top with no pinging or burbling. I ride in Fl which is at sea level and the temp is in the high 80's low 90's. With that being said, should I still experiment with different jetting to get more power or leave it alone?

If your happy with the way it runs leave it alone

Thats what I was thinking too. My only complaint about the bike is that it won't pull very hard out of a tight corner in 3rd gear. But I'm sure a 50 or 51 rear sprocket will take care of that.
